MATH 225 Week 2 Assignment; Frequency Tables and Histograms

Question According to the histogram, which range of length (in inches) contains the longest sampled Eastern diamondback rattlesnake? Answer 1: Not quite - review the answer explanation to help get the next one. $$greater than 87.5 but less than 90.5 Answer 2: Yes that's right. Keep it up! $$greater than 96.5 but less than 99.5 Answer Explanation Correct answers: $\text{greater than }96.5\ \text{but less than }99.5$greater than 96.5 but less than 99.5 The range 96.5−99.5 is the rightmost bar in the histogram, which means that this range of values contains the longest length. Therefore, 1 Eastern diamondback rattlesnake was recorded as having a length of greater than 96.5 but less than 99.5 inches. Question 2642256383895Select the answer that best describes the shape of the given histogram. A histogram has a horizontal axis from 0 to 16 in increments of 2 and a vertical axis labeled Frequency from 0 to 10 in increments of 2. The histogram contains vertical bars of width 1 starting at the horizontal axis value 0. The heights of the bars are as follows, where the horizontal axis label is listed first and the frequency is listed second: 0, 0; 1, 0; 2, 0; 3, 0; 4, 4; 5, 5; 6, 5; 7, 5; 8, 5; 9, 4; 10, 5; 11, 5; 12, 6; 13, 5; 14, 0; 15, 0. 913764-811343Well done!

Question A professor gave students a test, and the distribution of the scores of the students is shown in the histogram below. What shape best describes the distribution? A histogram has a horizontal axis labeled Test Score percent from 0 to 100 in increments of 20 and a vertical axis labeled Frequency from 0 to 15 in increments of 5. The histogram contains vertical bars of width 10 starting at the horizontal axis value 20. The heights of the bars are as follows, where the left horizontal axis label is listed first and the frequency is listed second: 20, 1; 30, 2; 40, 4; 50, 8; 60, 8; 70, 5; 80, 4; 90, 1. All vertical coordinates are approximate. Perfect. Your hard work is paying off 😀 92201911604659220191587820uniform 92201949230 unimodal and symmetric 92201949544 unimodal and left-skewed unimodal and right-skewed bimodal Answer Explanation Correct answer: unimodal and symmetric unimodal and symmetric Since there is a single peak near the middle and the two sides are approximately mirror images of each other, the histogram is unimodal and symmetric. Question The author of a book wants to know what price his book is being sold for. He gets the price from all the bookstores in a city and creates a histogram of the results. What is the shape of the distribution? A histogram has a horizontal axis labeled Book Price in dollars from 8 to 13 in
